An over speed control circuit for a wind turbine generator is disclosed which optimizes the time that the wind turbine generator is operational and thus maximizes the power output over time. The over speed control circuit forms a closed feedback loop which periodically measures the output voltage of the wind turbine generator in order to regulate its speed by electronically controlling the load on the generator. The over speed control circuit in accordance with the present invention is adapted to work in conjunction with known over speed protection lock out relays. More particularly, the over speed control circuit causes a short circuit to be placed the generator terminals when the generator voltage reaches a threshold value, relatively less than the threshold value used to trigger the over speed lockout relay. As such, the over speed control circuit minimizes the operation of the lockout relay, thereby maximizing the power output of the generator over time making such wind turbine generator systems much more practical as a renewable energy source.
